Magnetic Position Sensors

Linear Hall-Effect Sensor ICs with Analog Output Available in Miniature, Low-Profile Surface-Mount and SIP Packages

A1388-9

These parts are in production but have been determined to be NOT FOR NEW DESIGN. We recommend the A1308 as a replacement part. The A1388 and A1389 are high-accuracy, temperature-stable linear Hall-effect sensor ICs for displacement and angular position. They feature end-of-line optimization for sensitivity and QVO, programmable temperature coefficients, and a ratiometric voltage output, operating across -40°C to 150°C.
